Application fina May' 1s, 1905. serial No. 266.251".

To all whom zit-may concern.:-

Be it known that I, HENDERSON P. CHIL- DREss, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Cotton-Picker, of which the following i'sa specification. Y

Thisjnvention relates more particularly to improvements in that type .of cotton-picking machines disclosed in copending applications Serial Nos. 225,106, 241,690, and 244,240.

One of the principal objects is to prov-ide novel `manually-directed cotton picking and carnving means that has a wide range of movement with respect to the carrier and-wherein the movable elementswill not interfere with the change of position of said means.

y A further object is to employ in connection with a cotton-engaging belt supporting means therefor that Willkeep said belt taut Without regard to its change of position and to, further more, provide -means for mounting. said belt that will permit the relative movement ofthe different parts of the supporting means.

The preferred embodiment ofthe invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of a portion of a carrier-vehicle,showing one of the cottonpicking means. Fig. 2 is a plan View of the same. Fig. 3 is a vertical sectional View on an enlarged scale. Fig. 4 is a detail sectional,4

the manually-directed supporting member. Fig. l0 is a detail perspective view of a pair of the hinge-ears employedfor connecting the members. Fig. 11 isa detail sectional view through a modied con'structionofI hanger member.- Fig. 12 is a detail perspective'view of aportion ofthe'belt. Fig. 13 is a similar view of a slightly-modified and simpler form of belt. Y

Similar reference-numerals designate corresponding parts in all the iigures of the drawings. In the embodiment illustrated a portion of, the carrier-vehicle is shown and is designated generally by the reference-numeral 12. Pro- Asuitable mannerfas, for instance,

lvehicle and extendingV in advance .comprise tubular sections 2 -In the modified structure illustrated carrying means, which maybe driven. in -any by means such as illustrated inthe above-mentioned applications. Secured to 'the front'endjof the tliereof is a pair lof lstationary 4tubular supporting members 13 and 14, held in position by a suitable bracket 15. Suspended from the outer ends of these members are hanger members, (designated, respectively, as 'a whole by the reference-numerals 16 and 17.) The upper ends'of the hanger members are connected tothe outer ends of the statinary members by hinges comprisinglcollars 17", mbunted on the adjacent end andhaving leaves-18, provided with overlapping leyes 19, through which are passed pintles 20. v' The' hanger lmembers 16 and 17 preferably per of which areprovided with sleeves 23,- in

'which the upper ends"`of the lower sections 22 are slidably fitted. Coiled springs 24, surrounding the sections, bridge the joints thereof and are abutted against shoulders 25, formed 'on the sections, said springs thus' forcing the' sections away from each other. Connected to the lower ends of the hanger members are manually -directed members` (designated, respectively, 'as a whole, by the refe erence-numerals 26 and 27,) the rear ends of said members and the lower members being provided 28, connected by'fpintles 29'.. The manuallydirected members 26 and 27 comprise sections 30 and 31 lin theform of tubes that are connected by tubular spring-hinge portions 32,

with hinge leaves 1 and 22, the upif? ends of the'hanger 1 which permit the relative lateral movement i of the sections.

Mounted Ona suitable driving-Staines in` the vehicle is a driving-pulley 34. and run-` ning upon this pulley is anendless, cotton picking and carrying belt 35, one 'of the sides thereofl being provided with al narrower section, having suitable outstanding teeth 36. in Fig. 13 a belt 35 is employed, and projecting therefrom are staggered teeth 36". The active stretch of thisbelt operatesthrough the upper orouterset of supporting members 13, 16, and 26, while the'return stretchoperates through the members 14,'- 17 and 27, said stretches thus bridging the joints between the members. bers constitute housings for the belt as well It will thus .be seen that the mem.

as 'guides for the cotton carried by said belts.;

In order to prevent friction and 'wear of the belt the belt operate upon the peripheral faces of the flanges Vof this pulley, while the teeth .thereof move between the same, suliicient space being afforded between the teeth and the hub to permit the passage of cotton car-l ried by the teeth. A doifer-brush 41a operates against the belt contiguous to the'driving-pulley 34 to remove the cotton from the be t.

At the outer free ends of the manually-directed members 26 and 27 is mounted upon brackets 42 a pulley 43, about which the belt passes, said belt thus projecting fromthe pulleys in order to 'provide a cotton picking or engaging portion. The return stretch of the belt in like manner passes over pulleys at the joints between the members, a pulley 44 being mounted on the pintle 20 at the joint between the members 14 and 17, saidl pulley, as illustrated in Fig. 5, consisting of spaced flanges 45, upon which the side margins of the belt operate, said flanges being spaced apart to permit the unobstructed passage of the teeth 36. On the pintle 29, that is located at the joint between the members 17 and 27, is located a pulley 46, over which the belt operates.

By reference to Figs. 3 and 9 it will be ob served that theI ends of the manually-directed memberare arranged with their side faces sub-` stantially horizontal, passingoversuitable roll# ers 47. In order, however, to permitthe lateral flexing of the members at the joints 32,4 the belts are turned on edge, and for this purpose upright rollers 48 are journaled in the sections 31 contiguous to their inner ends, said rollers thus guidingl the belt to upright position at the joints. Other guide-rollers 49 are located in the hanger members and in the stationary supporting members, as illustrated in Fig. 3. Y

ln order to prevent the slipping ofthe d riving-pulley 34 upon the belt, a friction-roller 5() is employed, which, as shown in Figs. 6 and 7, consists of va 'hub 51, journaled on an axle 52 and having spaced flanges 53, that bear against the side margins of the belt to hold the same in frictional engagement with the roller, said flanges permitting the passage, of the tfethof the belt. The axle 52 is carried by a yoke 54, that is mounted on a stem 55, slidable in a supporting-bracket 56. A spring 57, located on the stem and interposed .wardly without interference.

suceso abutments 24, secured tothe sections.4

lin actual practice apair of themechanisms are employed for each operator', as shown in Fig. 2, the rear ysections of the manually-directed members being preferably divergently disposed and the front sections being substan- ,tially in the ferm of elbows and convergently Power being applied to the driveshaft 33 in the direction illustrated bythe disposed.

arrow in Fig. 3, it will be evident that the upper and .outer stretches of the belts will be moved rearwardly through the supporting members. The operator has only to direct the ,in either-direction', as indicated in dotted lines in Fig. 2, orcan turn the membersas a whole,

as also shown in dotted lines.' He may, furthermore, swing the hanger and manually-dim rected members freely forwardly and back- Moreover, in any position the belts will be kept taut, as the sections of the hanger members will be yield- '.ingly forced apart by the various springs or drawn together by the tension of the belts when turning the same in different directions. From the foregoing it' is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art withoutfurther description, and it will be'understood that various change'sin the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.l
